[0003] The swash plate axial piston pump is the most representative type of piston pump. The existing modeling technology for the swash plate axial piston pump mainly uses the swash plate spherical assumption for analysis. The calculation process Complicated, slow calculation speed, low analysis efficiency

In addition, the existing modeling technology completely relies on the mechanical structure design of the specific plunger pump when analyzing the effect of the adjustment mechanism on the swash plate, making the analysis method not universal and universal

In addition, the output results of the existing modeling technology can only represent the average value of the output flow of the plunger pump, and the average output flow and the instantaneous output flow value of the plunger pump during the working process cannot be obtained based on the same modeling technology.
